Compare for example with MGM's properties in Las Vegas which they claim consume 171 MW. That's not quite as much as Bitcoin, but it's still higher than 65 of the countries listed here: https://en.wikipedia.org/wiki/List_of_countries_by_electrici...

So it's actually pretty easy to surpass the usage of "an entire country". And that to me seems like a much more useless waste than Bitcoin, which has significant uses besides entertainment
